我想touchMove的时候执行animation

可以console.log出来animation对象

可是动画不执行

请问问题出在哪?

Page({

/**

data: {

navArray: [],

baseSize: 5,//基数，为了不顶边

offsetLeft: 5,//设置初始距离

linehidden: true, //导航下小横条显示

startX:0,

endX:0,

moveX:0,

animation:{}

},

// Touch处理函数

navTouch: function (e) {

var that = this;

var navPage = e.target.dataset.type;

var baseleft = that.data.baseSize;

var offsetLeft = e.target.offsetLeft + baseleft;

that.setData({

offsetLeft: offsetLeft,

navPage: navPage

});

},

onReady: function () {

var that = this;

that.animation = wx.createAnimation({

duration: 1000,

timingFunction: ‘ease-in-out’,

});

},

touchStart:function(e){

var that = this;

var startX = e.touches[0].pageX;

// console.log(startX);

that.setData({

startX: startX

})

},

touchEnd:function(e){

var that = this;

var endX = e.changedTouches[0].pageX;

that.setData({

endX: endX

})

},

touchMove:function(e){

var that = this;

// console.log(e);

var moveX = e.touches[0].pageX;

var startX = that.data.startX;

var transX = (moveX - startX) + ‘rpx’;

that.animation.translate(transX, 0).step();

console.log(transX,that.animation);

that.setData({

animation: that.animation.export()

})

}

})

console结果
